IMPROVEMENT IN CU LTIVATORS.

Specification forming part of Letters Patent No. 133,067, dated November 12, 1872; antedated November 11,

To all whom it may concern:

Be it known that I, JAMES G. STOWE, of

Bloomington, in the county of McLean and in the State of Illinois, have invented certain new and useful Improvements in Cultivators and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in .the construction and arrangement of a cultivator, as more fully hereinafter described.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a perspective view of the entire cultivator. Fig. 2 is a side view of one of the plow-beams, partly in section, showing the modes of attaching the shovels. Fig. 3 is a section through the coupling between the frame and plow-beam. Fig. 4 is a rear view of one of the shovels.

A A represent the two branches of the split tongue, which run together at the proper distance in front of the wheels, and are held in suitable position by the bottom bar B and the top bar 0, both of iron. The ends of the bottom bar B are bent perpendicularly downward immediately outside of the beams A A, while the ends of the top bar 0 extend beyond said beams for a suitable distance, and then bent perpendicularly downwardand then horizontally inward, connecting with the extreme ends of the bar B. D D are braces connecting the ends of the bar B with the ends of the beams A A. At a proper distance from the frame the two branches of the tongue are connected by a short cross-bar, E, and to the same is pivoted the double-tree G, from each end of which depends a metal bar, H. These bars H H areperforated to attach the single-trees at any height desired, and said bars are, by rods a a, connected with the lower part of the bent bar 0.

The above forms the frame of my cultivator, which, at the same time as it is light and easily handled, is nevertheless strong and durable.

It can be. readily made and easily repaired by any mechanic, if out of order.

Upon the lower horizontal part of the bar 0, at each end, is attached the coupling I J, forming the connection between the frame and the plow-beams. This coupling consists of a cup, I, provided with flanges b b on its under side to fit over the edges of the bar 0, and the cup fastened by a bolt and nut, d, as shown in Fig. 3. This cup may be moved out or in, at pleasure, on the bar G by having a number of holes in said bar, thereby moving the shovels or plows further apart or closer together, as may be desired. Around the periphery of the cup I is a semicircular or other suitablyshaped head, 0, which fits in corresponding grooves on the inner circumference of two semicircular jaws, J J, which complete the coupling. These jaws are, at each end, pro vided with ears f, and the two cars at the front are connected by a bolt or rivet, as shown, while the cars at the rear are connected by a bolt and nut, which also pivots a bar, K, between said ears. To this bar K the two plow-beams L L are rigidly attached, said beams being made of tubing of suitable size and bent in proper shape, with shovels or plows M M attached on their rear ends.

It will be noticed that, by means of this coupling, the plow-beams may be raised and lowered, and also turned sidewise, as occasion may require.

The shovels M are each'bolted or riveted to a metallic block, 00, connected to which is a tubular receiver, h, on its rear. These tubular receivers are each provided with a slot, 2, cut therein at right angles with the plow-beam, or short piece m, which may be fitted within them. A bolt, 70, is placed within each tube h, with its bead on the inside. The lower ends of each beam L, or each piece m, have a slot, y, which opens at the lower end. The bolt 1s held in the slot by a nut and washer, as shown. The tubular receiver and block may be made in one or two pi eees, as preferred. The shovel is attached to the block as, and the bolt 76 and nut to the tube. The slotted end of the tubular beam or the slotted end of the piece m rs then passed into the tube, so that the slot rs around the bolt and the head of the bolt 1s within the tubular beam or piece m. The nut is then screwed on tightly, and effectually clamps the parts together. By means of the cross-slot z the shovels may be placed at a suitable angle, and, by means of the vertical slot 3 in the beam L or piece m, the shovels may be raised and lowered, and the connection easily and quickly made. The plowbeams L L may be made each in one piece; or the rear end may be a separate piece, and the shovel attached to this piece, which is marked m in the drawing. The piece m is, at its upper end, provided with a tongue, 11., which is pivoted in a slot in the end of the main part of the plow-beam, and its upper end fastened or held by a wooden pin, so that if the shovel should strike a stone or other solid obstruction this wooden pin will break and allow the shovel to turn backward over said obstruction.

On top of the cultivator thus constructed I place a tool-box, N, fastened by a bolt through the bars 0 and B.

In place of the tongue at being on the small piece m, it may be on the main part of the beam and work in like manner in the piece m Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-- 1. The combination of the cup I, having flanges b b and circumferential head 6, with the jaws J J having ears f f and a groove on the inner circumference corresponding with the bead on the cup, substantially as and for the purposes herein set forth.

2. The combination of the shovel, carryingblock 00, tube h, cross-slot z, bolt 70 with bead inside the tube, with the tubular beam L (or tubular piece m) with open-end slot 3 all secured together by the nut on the exterior, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of March, 1872.
